Re: [aspectj-users] Annotated method parameters and wildcards

["Eric Bodden" <eric.bodden@xxxxxxxxxxxxxx>]

Hi Srdan.

The only think you can do in this case is to match on *any* method
that has an @NonNull annotation and then use thisJoinPoint.getArgs()
in the advice body to expose the arguments from there.

Also you should look at Contract4J, as it does exactly this (and more)
using AspectJ: http://www.contract4j.org/contract4j
